Ottoman prayer rug, 16th century. Istanbul or Cairo. Turk ve Islam Eserleri Muzesi, Istanbul

John Taylor's notes on this carpet: "A fragment in the Turk ve Islam Museum was brought from the Sultan Ahmet Mosque with a remark that it had been made in Istanbul. Also a first rate quality,and again hard to say if lamp and panel were originally present.This carpet spawned a number of later pieces."
